CairoMatrix::initRotate -- cairo_matrix_init_rotateCreates a new rotated matrix


Estilo orientado à objeto (method):

public static CairoMatrix::initRotate ( float $radians ) : void

Estilo procedural:

cairo_matrix_init_rotate ( float $radians ) : object

Creates a new matrix to a transformation that rotates by radians provided



angle of rotation, in radians. The direction of rotation is defined such that positive angles rotate in the direction from the positive X axis toward the positive Y axis. With the default axis orientation of cairo, positive angles rotate in a clockwise direction.

Valor Retornado

Returns a new CairoMatrix object that can be used with surfaces, contexts, and patterns.
